Fig. 1 is a circuit block diagram of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
Among the figure: 1-solar panel, 2-overcharge protection circuit, 3-batteries, 4-over-discharge protection circuit, 5-Voltage stabilizing module, 6-control circuit, 7-control electronic circuit, 8-light-operated circuit, 9-LED lamp group, 10-drive circuit, 11-infrared induction circuits for triggering.
The specific embodiment
As shown in the figure, as shown in the figure, solar panel 1 is installed in the top of lamp body shell, and batteries 3, control circuit 6 and LED lamp group 9 are arranged in the lamp body.Daytime, solar panel 1 is accepted solar irradiation after D1 charges to batteries 3, when batteries 3 chargings are saturated, D2 falls to lead to provides voltage to triode Q1 base stage, triode Q1 conducting with the short circuit current of solar panel 1, makes electric current protected, triode Q1 has constituted overcharge protection circuit, has the function of protection batteries 3 and solar panel 1; When electric current during, the LED lamp group 9 of can not flowing through, prevent that LED lamp group 9 from burning because of the electric current that passes through is excessive by short circuit.When switch closure, through Voltage stabilizing module 5 (voltage stabilizing triode HT7144A), output voltage 4.4V, the electric current of batteries 3 enter 2 pin, light-operated module 8 and the infrared induction circuits for triggering 11 of one-chip computer module by resistance R 5.The characteristics of this one-chip computer module are that its 5 pin voltage just changes with 2 pin voltages, and promptly when 2 pin were high level, 5 pin also were high level output; When 2 pin were low level, 5 pin also were low level output; And one-chip computer module has delay function simultaneously, when 4 pin of one-chip computer module are triggered, 6 pin will be delayed time output, delay time 30-60 second, time-delay 30-60 in second, 4 pin touch inoperative, wait time-delay 30-60 after second in 2 seconds, 4 pin trigger inoperative, after 2 seconds, trigger and still delay time 30-60 second, circulate with this.Described light-operated circuit 8 is made up of photo resistance CDS and resistance R 5, and photo resistance on daytime CDS is a low resistance, and 2 pin of one-chip computer module are electronegative potential, the output of 5 pin low levels, and electrolytic cell power supply C1 discharges to triode Q6; Evening is when being lower than 100LUX when light, the resistance of photo resistance CDS is very big, the electric current of flowing through is very little, and one-chip computer module 2 pin are high level, and 5 pin are high level output, one-chip computer module 5 pin link to each other with triode Q6 through resistance R 7, because 5 pin are high level output, then triode Q6 conducting, triode Q6 drags down the B utmost point of triode Q8, triode Q8 conducting, 9 conductings of LED lamp group are luminous.When the electric current of one-chip computer module 5 pin outflow was excessive, 5 pin linked to each other with triode Q5, Q4 through resistance R 4, and unnecessary electric current is released in the electrolytic cell power supply C1, had realized crossing the effect of putting protection.(concrete principle is: when triode Q4 conducting, and triode Q3 conducting, D3 is conducting also, the conducting of triode Q10 base stage high potential, triode Q2 base stage is also conducting of electronegative potential triode Q2, and LED lamp group 9 voltages are supplied with by triode Q2, and LED lamp group 9 is shinny.When batteries 3 voltages are lower than 5.6V, D3 ends, and this moment, triode Q4 base voltage was an electronegative potential, triode Q2, triode Q3, not conducting of triode Q4, and LED lamp group 9 does not have electric current to flow through, and realizes protection.)
The lamp body shell left and right sides is provided with an inductive probe PIR respectively, when inductive probe PIR receives infrared signal, be input to 14 pin of signal amplification module through R12, carrying out the computing first time amplifies, amplify output from 16 pin computings, through capacitor C 4 couplings, 13 pin second level operational amplifiers of entering signal amplification module are exported anti-phase input, amplify in inside, two-phase mirror spoke device is through state controller, by the 2 pin output of signal amplification module, the characteristic of signal amplification module is when its 9 pin is high level, and state controller just has signal output.Evening is when being lower than 100LUX when light, the resistance of photo resistance CDS is very big, and one-chip computer module 2 pin are high level, and 5 pin are high level output, 9 pin of the signal amplification module that link to each other with 5 pin this moment also are high level, and the signal after state controller will amplify is through the 2 pin output of signal amplification module.When 2 pin of signal amplification module are given high potential triggering signal of one-chip computer module 4 pin, one-chip computer module 6 pin time-delay output in 60 seconds, high-potential current links to each other with triode Q7 through resistance R 6, and triode Q7 drags down the B utmost point of triode Q9, triode Q9 conducting, also conducting is luminous for LED lamp group 9.
Operation principle of the present utility model is: when the night fell, photo resistance CDS is a high impedance, and 2 pin of one-chip computer module are high level, and IC is started working, the 5 pin high level output of one-chip computer module.One the tunnel removes to drive triode Q5 through resistance R 4, makes triode Q2, Q3, Q4, Q10 conducting in succession; Another road drives triode Q6 through R7, makes the Q6 conducting, and 1 LED lamp is bright.When hot outer induction probe detection goes out the infrared ray that human body sends, can export a signal, this signal is after signal amplification module front and back stages amplifier is amplified, 2 pin output high level from the signal amplification module, 4 pin of this level triggers one-chip computer module make 6 pin of one-chip computer module export high level, drive triode Q7, Q9 through R6, light 33 LED lamp, and delay time 30-40 second.Behind the 30-40,33LED extinguishes during the court of a feudal ruler. and arrive up to next infrared signal, repeat above work.
